Grey Rock Block Synchroniser for Wordfence and Cloudflare

Grey Rock Block Synchroniser connects Wordfence block intelligence with Cloudflare edge enforcement. When Wordfence identifies qualifying hostile activity, Grey Rock can report the address to Cloudflare so future requests are stopped before they reach WordPress. The result is a practical defense-in-depth feedback loop designed to make a website less rewarding to repeat attackers.

Why is Greyscale.zone greyscale?

Communications, Measurement and Standards, Science and Technology / Linus

Greyscale Zone uses greyscale as a way of paying attention. The name is not about rejecting colour. It is about choosing a lens.

Why I Added a GPS NTP Server to My Home Lab

Home Lab, Measurement and Standards / Linus

GPS NTP Server Accurate time is one of those things most people do not think about until something breaks. In a basic home network, that usually does not matter much. A router, laptop, phone, smart TV or streaming box quietly gets time from the internet. Most people never see that happen. But once a home
